1.Requiem For A DreamOne of the many functions of the film is to shed light on human nature. Thus, the desire to be inseparable from human nature is treated very importantly in the film. Darren Aronofsky's "Requiem" deals with the self-destructiveness of vain desires through the tragedy of addiction caused by scarcity, among many aspects of human desire. In Requiem, Sarah, a middle-aged woman, her son Harry, Harry's lover Marion and Harry's friend Tyrone all have a common lack of human bonds and communication. To satisfy this lack, each person chooses intemperance and instant pleasure: drugs. This choice allows the four characters to lose control and patience and fall into the path of enjoyment, which shows the bare face of a self-destructive desire that follows a distorted desire to fulfill its deficiency and faces a tragic end. Like this, "Requiem," which shows human self-destructive desires, is different from other films dealing with drug addiction in that it conveys a person's psychological state and physical sense with unconventional and bold editing techniques.
